CNC Sinker EDM Copper from VT machining delivers precision Copper parts produced to your exact drawing. Sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features, and we tune every parameter to the behaviour of Copper, which is excellent electrical and thermal conductivity.
CNC Sinker EDM Capability for Copper
- Blind cavities & ribs
- Fine surface (VDI grades)
- Tolerance to ±0.005 mm
- Hardened tool steel
Applications of CNC Sinker EDM Copper
Typical uses for CNC Sinker EDM Copper include precision Copper components for electronics, instrumentation, automotive, medical and energy applications.
How CNC Sinker EDM Copper Works
Our CNC Sinker EDM setup for Copper starts from your CAD model. The program, tooling and parameters are selected from the part geometry and the known behaviour of Copper, then verified on the first article.
Why Copper for CNC Sinker EDM
The reason customers specify Copper for CNC Sinker EDM is straightforward — it is excellent electrical and thermal conductivity. We handle the grade selection and any heat-treat or condition requirements with you.
CNC Sinker EDM Quality & Inspection
Each Copper part is inspected against your drawing, with critical dimensions verified before the batch is released. Documentation can be provided on request.

Does CNC Sinker EDM Copper require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Can VT machining make custom Copper parts to my drawing?
Yes. Copper Copper EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What tolerances can you hold for CNC Sinker EDM Copper?
Achievable tolerances for Copper EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
Can you EDM-machine hardened Copper?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Copper can be machined to fine detail and tight tolerance without distortion.
